Ok.... I was bored and looking around at the various bolt-on possibilities that I plan to purchase for the new Camaro. I had a question about ported headers though.... without sounding like an idiot, what exactly does it mean for the exhaust manifold to be "ported"? I know that it increases flow, but what is the difference betwen a ported header and a non-ported header?
